AI Technical Summary

Problems solved by technology

In the process of processing, the power consumption is quite large, the cost is high, and there are defects in environmental protection and production efficiency. Compared with liquid dosage forms, there is a certain gap in drug efficacy.
Liquid formulations include 5%, 10% emulsifiable concentrate and 10%, 20% soluble liquid, all of which use a large amount of benzene, toluene and other organic solvents, which waste a lot of resources and pollute the environment

Embodiment 1

[0024] Add 150kg of tap water, 150kg of polyphosphoric acid, 60kg of sulfuric acid, and 80kg of oxalic acid into the reaction kettle, then slowly add 420kg of 95% imidacloprid to dissolve it completely, filter, then add 20kg of JFC, 50kg of TW-80, and 20kg of TW-20, After stirring evenly, make up the balance to 1000kg with water to obtain 1000kg of 40% imidacloprid microemulsion.

Embodiment 2

[0026] Add 200kg of tap water, 140kg of polyphosphoric acid, 50kg of sulfuric acid, and 120kg of oxalic acid into the reaction kettle, then slowly add 55kg of 95% imidacloprid to dissolve it completely, filter, then add 30kg of JFC, 60kg of TW-80, and 30kg of TW-20, Add water to make up to 1000kg, and after stirring evenly, 1000kg of 5% imidacloprid microemulsion is obtained.

Embodiment 3

[0028] Add 200kg of tap water, 150kg of polyphosphoric acid, 50kg of sulfuric acid, and 90kg of oxalic acid into the reaction kettle, then slowly add 320kg of 95% imidacloprid to dissolve it completely, filter, then add 20kg of JFC, 50kg of TW-80, and 20kg of TW-20, Make up the remainder to 1000kg with water, and after stirring evenly, 1000kg of 30% imidacloprid microemulsion is obtained.

Abstract

The invention discloses an imidacloprid micro emulsion type insecticide, wherein the percentage by weight of the constituents being, imidacloprid 5-40%, polyphosphoric acids 14-16%, sulfuric acid 5-6%, oxalic acid 8-12%, emulsifying agent 8-12%, and balancing water. The invention features in high activity, low cost, easiness in application and high insecticidal efficiency.

Description

Technical field: [0001] The invention relates to a pesticide preparation, in particular to an insecticide for preventing and controlling pests with piercing-sucking mouthparts such as rice, wheat, cotton and potatoes. Background technique: [0002] Imidacloprid is a new type of insecticide with high efficiency, low toxicity and broad spectrum. It has a good control effect on the piercing and scraping mouthparts pests of resistant strains such as aphids, leafhoppers, planthoppers, and thrips. [0003] imidacloprid, [0004] [0005] It is a colorless crystal at room temperature. Its melting points are 143.8°C and 136.4°C respectively, and it is hardly soluble in other organic solvents except for its high solubility in dimethylformamide (DMF about 20%) and dichloromethane (about 10%). Decomposed in strong acid, imidacloprid is generally processed into two dosage forms of wettable powder (5%, 10%, 25%) and suspension concentrate (35%, 40%, 70%). In the process of processi...
